Description

П р И м ер. На предпри тии проводилась сушка литейных керамических (этилсиликатных) форм методом погружени  их вжидкий азот, с криогенной температурой (температурой конденсации ) в сосуде Дьюара ниже 120°К, и выдерживани  их в нем до самопроизвольного улетучивани  газа(4,0 мин).Pr and m er. The company carried out drying of casting ceramic (ethyl silicate) forms by immersing them in liquid nitrogen, with a cryogenic temperature (condensation temperature) in a Dewar vessel below 120 ° K, and keeping them there until spontaneous volatilization of the gas (4.0 min).

При этом короблений не замечено.At the same time warping is not noticed.

Перед заливкой многоместна  керамическа  форма была прогрета путем помещени  её в остывающую печь (Т остывани -800 С) и выдерживани  в ней дл  выгорани  воскового состава в течение 0,5 ч.Before pouring, the multi-part ceramic form was heated by placing it in a cooling oven (cooling temperature -800 ° C) and keeping it in place to burn out the wax composition for 0.5 h.

В подвергнутую сушке жидким азотом и подогретую керамическую форму был залит жидкий металл.- бронза АЖНМу 9-4-4-1.Liquid metal was poured into the dried liquid nitrogen and the heated ceramic form. Bronze AZNM 9-4-4-1.

Качество отлитых деталей хорошее .The quality of the cast parts is good.

Использование предлагаемого способа сушки литейных форм и стержней обеспечивает по сравнению с существующими способами следующие преимущества: уменьшение затрат энергииUsing the proposed method of drying foundry molds and cores provides the following advantages compared to existing methods: reducing energy costs

дл  изготовлени  керамических форм и стержней; увеличение производительности изготовлени  форм и стержней; увеличение пропускной мощности участка сушки форм; исключение коробле-, ни  форм и стержней в процессе сушки; расширение номенклатуры обрабатываемых форм и стер ей.for making ceramic molds and rods; increasing the productivity of manufacturing molds and cores; an increase in the throughput capacity of the mold drying area the exclusion of the box, no forms and rods in the drying process; Expansion of the range of processed forms and erased it.
